To all whom it may concern: p

Be it known that we, ALBERT C. TEEREIIL and STILAS MCCLURE, of Oskaloosa, Mahaska county, Iowa, have invented certain new and useful Improvements in Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings and. to the letters of reference marked thereon.

Our invention relates particularly to Woodburning stoves; and its object is to provide the same with a series of easily-removable hot-air iiues and with a hot-air draft so constructed and so located that the combustion and heat conserving qualities of the stove are greatly improved. This we accomplish by the employment of removable devices in the bottom of the stove which anchor the lower ends of said air-fines, and by means of a hotair draft-tube of peculiar construction which takes the air from a point at the side of the stove above the re-bed and conducts it to a point at or below the fuel and discharges it in a heated condition into said 4lire-bed, substantially as hereinafter fully described, and as illustrated in the drawings, in which* Figure lis a vertical central section of said improved stove. Fig. 2 is a horizontal section therethrough, takenon dotted line 2 2, Fig. l. Fig, 3 is an elevation of thesame, and Fig. et is a vertical section'on the line 4 a, Fig. 2.

Having reference to the drawings, A represents the exterior shell of our improved stove, which in the drawings is shown to be elliptical, but which may be cylindrical or square or any other shape desired. This shell is provided with a suitable cast or pressed steel top B, more or less ornamented, substantially as shown, and provided with a fuel-opening a in the forward portion which is closed by a suitable cover b, and provided with a stovepipeopening c in the rear portion, into the upwardly-projecting annular flange c of which the stovepipe C istelescoped in the usual manner. The shell A is .also provided with a suitable sheet-steel bottom D, which is fastened thereto by a double seam or otherwise, as desired. In the side ofthe shell, at a point preferably nearer the top of the stove,is a draft-open-` ing E,'which has a cast-metal rim'd riveted to the margins thereof on the outer side, and is closed by a door F, having a common form of oscillatory register made therein, so as to regulate the ingress'of air. Secured tothe margins of the inner side of openingE, preferably'by the same rivets used to secure rim d, passing through its iiange, is a draft-tube G. The draft-'tube leads yfrom the draft-opening E, and its shape is such that it bends downward and extends toward and terminates at a point a short distance above the bottom of the stove. At the top'the .diameter of the said tube G corresponds to or is slightly greater than the draft-opening; but it gradually decreases in diameter as it extends toward its lower end, which latter is turned toward and discharges the heated air from its lower opening toward the center of the iire-bed of the stove.

It is vwell known that heated air projected into burning fuel. promotes combustion and does not condense the heated products of combustionas does cold air. `Thedraft-tube G is an economical improvement to the stove and is provided for this very purpose. It is made tapering toward its lower end, so as to make it forcibly eXpel the heated air in a manner greatly exceeding the force of the natural draft, were the tube of the same diameter throughout its entire length.

The top B ofthestove audits bottom D are each provided with a series of openings h and g, respectively, and each of the series of openings 7e in the said top is arranged in vertical alinement with some one of the openings g in the bottom and are connected thereto by sheet-metal tubes H. In order to removably secure these tubes inthe stove, so that should they burn or rust out they could be removed and replaced7 we provide each opening in the top B with a downwardlydepending integrant annular flange h', over which the upper end of said tubes telescope. For each opening in the bottom of the stove we provide an angle-iron ring K, the vertical portion of which is slightly tapering toward its end. edges and is of a maximum diameter corresponding to that of the bore of said tubes H. l

yIn use we insert the tubes H into the stove and telescoping or tting their upper ends over the anges of the opening h (with reference to which it is used) bring it vertically IOO into concentric alinement with the fellow opening in the bottom D. XVe then insert the tapering vertical portion of the angle-iron ring K up through the opening g into the bore of tube H and then bolt or otherwise removably secure Ithe rings to the bottom D by bolts 7s, as shown, or in any suitable manner. In this way should any of said tubes require removal all that it is required to do is to remove ring K, and by pulling the lower end of the said tube laterally it can be removed without disturbing the other tubes and another tube inserted to replace it and be secured in place, as hereinbefore described.

Te lay no claim to the particular arrangement of tubes ll, although for convenience we have, as shown in the drawings, placed six of said tubes on each side of the fire-bed. Any other arrangement, however, would answer.

\Vhat we claim as new is- A stove consisting of a top having a suitable stovepipe-opening and fuelopening therein, and provided with a series of openings h therein, each having an annular lange made homogeneous with the top and extending down into the stove from its edges, a shell to the top edges of which said top is sccured, and a bottom having a series of openings g therein, each of which is in Vertical alinement with some one opening h in said top, in combination with a series of tubes arranged in vertical alinement between companion openings in said top and bottom, and with their upper end teleseoping over said flanges, and angle-iron rings K having their vertical portions slightly tapered and inserted np through openings g and into the lower ends of tubes K and removably secured to said bottom, as set forth.
